Veolia Water
Technologies South Africa is a leader in microfiltration, with a complete
range of membranes available. We provide turnkey MF solutions for industries
and municipalities, which can be both modular or part of an in-ground
civils-based plant. This includes customised operations
& maintenance contracts and quick turnaround on new replacements MF
membranes.

Microfiltration
in your water stream:

As with other membrane filtration processes, microfiltration
entails the introduction of a feed stream into the MF membrane under pressure.
The larger pore sizes of microfiltration membranes mean less pressure, and thus
energy, is required to extract the permeate, and is thus is extremely cost effective
in the relevant micron range.

In terms of molecular weight, membranes can separate
macromolecules of molecular weights less than 100 000 g/mol. The filters used
are specially designed to prevent particles like sediment, algae, protozoa and
large bacteria from passing through.

When used for potable
water treatment, the membranes are a key step in uptake water primary disinfection.
When treating secondary wastewater
effluents, MF is used to remove turbidity and provides treatment for
disinfection.
